Without this, quarantine learning would be impossible
dude fr lik ei understood none of what my teacher told me
Fax yo
It’s still really hard
@@BrawlStars-ei7pe yes but this helps A LOT for me

Does anyone else find his writing satisfying
I thought I was the only one who thought that... Well, at least I'm not alone. You can literally turn off the audio and then just watch him write. The most satisfying video I've seen so far.
NOPE I LUV IT
@@myorkka he should use that green more.
Yellow is more visible on black background. He should have used it. Red is not clear.
Maybe it's his hella neat handwriting.
Tfw this is more effective than my teacher
What's Tfw?
@@lowmashranpara4989 Acronym for “The face when.”
@@lowmashranpara4989 the fact when
Probably because its easier to teach this way
thank u sooo much Mr. Khan, as a Mom of a middle schooler and soon to be in high school, you have made my life as a Mom easier. I really appreciate your knowledge, and effort in mentoring millions of kids that needed to excel above and beyond with their math skills.
my teacher is failing to teach me and he helped
I'm fine
So your teacher failed to teach you and helped you at the same time? That is amazing ffs
@@turbocpt1 when @Random Human119 said "he" he meant the guy running the channel
@@saltypenguin0_o I know. I was sarcastically demonstrating the message portrayed by the comment, in context to the comment layout.
Everything done by Khan is perfectly paced and clearly explained.
good video khan. your video always help me to get good grades on school. we need more people like you
who's khan?
@@lostfreek1097 the guy on video?
@@gotofinancial no he's sal
LoStFreeK khan is this gu y
@@gotofinancial bro his name is sal
we're out for coronavirus and my teacher told us to use khan academy for he videos and work... OMG this guy is better than my own teacher!!
Teacher might have made a mistake pointing you here.
steven cooke yeah probably I haven’t learned a single thing over corona break 😂
It's 9:45pm the night before the maths test, and here I am learning what my maths teacher couldn't. thanks khan academy!
anyone here in quarantine stressin about their studies or are u guys normal?
Stressin dude
Stressing
Can’t even sleep properly from this dogshit
Can’t we go back to being cavemen
normal
this was uploaded the day i started them in class woah
That's cool!

I have difficulty understanding what my teachers are talking about because they all seem bad at explaining things but you make it so simple. And I love that because I love math and want to properly understand math.
I never payed any attention during high school math classes so I did horrendously. now that I’m going to college your videos have helped me make up for all the learning I missed out on.
Great, can't thank you enough, so helpful. Will look out for more of the same only different.
As an adult student needing a refresher, Khan academy has been a god send. Thank you so much!
I find it weird that I understand this better in English than my own Icelandic language.
The best thing about Khan Academy is that every single minor doubt and information is given in the video. In short they teach the topic from the root.
An absolutely beautiful explanation! Thank you!
Incredible video! No words can describe how useful these knowledge is for me. Thank you so much!
Your video's always help me and my school uses them
Such a clear explanation. Thanks!
didn't learn that in school 10 years ago.. Thanks Khan
Thank you so much. Well articulated and i have really understood.
Didn't under stood this at school but literally this educational page saved my grades...👍
this was very helpful! thank you!
Khan Academy is a great tool to be a step ahead of what your teacher is teaching you. Thank you Sal Khan, consistently watching your videos is making school a breeze for me : D
Perfect very good explanation. It's very simplified. Thanks a lot.
Really well explained video, thanks a lot!
When you scroll through the study group and somebody needs help with math you know
Bottom Text
I think i can understand you more than my teacher in math
Thanks SO much for this video! It helped a lot!! You are the best!
Check out Mathantics and Professor Dave and Socratica.
Thank you khan academy, very cool!
Thank you, life saver! Textbook definitions make it hard to understand.
Someone tell me I'm not the only one without audio on this video.
You help me alot
Does anyone know if this includes interceptions with cubics?
Thanks for the clrear interpretation
My brain has a constant rainbow wheel spinning and air is coming out of my ears. But thank you Doctor Khan.
This is a very nice video and I learned a lot from this video Sal
Shouldn't it be mononomial?
Yoo indian guy on youtube lets gooo
Thanks a lot! That's a really clean explanation... At this point in time I'm really trying to understand math
I agree
This is extremely helpful js
Hi all khan method is very easy that amazing....
my first time studying for a math contest with a huge prize, thank you for providing such easy and accesable lessons Khan Academy. Wish me luck guys
How’d ya do?
@@moonwatcher4047 i forgot but i remember i was near the 50th percentile among like 400 students lol. It was still a fun experience tho
nice video,but u also have some video about polar coordinate?
thanks for this video. it helps me a lot. :)
Exelent and clear explanation for the polynomials. Your videos always fill my gaps math. Thank you Sal.
I am a fifth grader who is going to take a test for Algebra I. This really helps.
I think coefficient of a term is any factor of that term whether it is a numerical coefficient or simply coefficient or whether it is a literal coefficient....but you said that only numerical coefficient is the only coefficient of that term however there are literals also waiting to get their chance as well....
Here are some monomial integers sorted in ascending order each divided by one: 1,2,3,4,5,6,7,8,9 - also known as counting.
haha nice one
Ok, good for you
Nice videos khan, what do you use for the visual elements, is it an app?
we started learning about monomers and polynomials in year 7
I didn't realize it was this simple
Really helpful 😊😀😀
Which software you use for writing. Please tell me sir
Looking at 5:22, can it be a polynomial if 'a' were greater than or equal to 1?
Thanks sir.
This channel is good but ilmkidunya is much better for metriculatin class 9,10,11. They make very well explained tutorials of all subjects and all chapters.
Keep up the good work👏
I did not know that a polynomial exists for only positive known integers. But now I know.
10 minutes from sal more effective from 30 lectures of my teacher.
Thank you man
I hope this helps me for algebra 1
Me too
سبحان الله وبحمده سبحان الله العظيم

Thanks. Can you tell me what your using to write? Like is it a pen or a mouse? Just wondering cause you have nice control
@KEVIN PENG thanks....2 years after I received my GED 😂 thanks for the help
@@f.d.english5080 😂😂
Better than my high school math teacher
Love from India🇮🇳
Teach us more
7:25
ty a lot
10x^3 - 2x^2 + 14x^1/2
My teacher said that this is a polynomial but the 14x is raised to a fraction so shouldn't it not be?
Bobby Fisher it's not a polynomial
I seeing this video in 2022.
Now i understand about polynomial
thank u! :)
why does everyone find these so helpful he should at least not make mistakes and then fix them without editing the mistakes out
Sir....in Wikipedia I found that "x" is called as indeterminate in polynomial expression but "x" is called as variable in polynomial function. I still can't get the difference mentioned in the Wikipedia about polynomial. Can you please explain me this clearly?
Thanks in advance 🙏
I need to know who narrates this his voice is so soothing
Logic Mathematics 👍🏻
The one thing that he didn’t talk about is whether you could have more than a single variable in a polynomial. Eg. 3x^2 + 2y^3
Another good 📹
Very helpful
Khan Academy!!
let's explore the notionnnn he looks tired there
Another rule you should watch out for is if, the polynomial has any terms that are being divided by a variable. If this is true then the formula is not a polynomial!
x times the nth root of y
Anyone please tell me if khan academy consists of entire CBSE portion!!!
woah
He teaches better than my teacher
Awesome
Stressing over two tests I'm retaking in an hour
At 3:44...9x^0 is not defined at x=0 since 0^0 is not defined. Then how can we say 9x^0=9 for all real x's?
At 7:23 minutes of the video jhan drew a happy face 😃
Shouldn't the exponent of 9x be 1, bcos x^0 is 1 therefore that is no longer 9x but 9(1). Please confirm. Thank you
thats what i was thinking!
U can never consider the value of x! U can't determine x as any number without exact proof! So it's better to take x^0=1 instead of taking the risk of considering x=1 ! Because when you take 9x as a term, it gives out lot of solutions, not just 9(1)! ☺
too good
+Khan Academy Let Q(X,Y)=2x^3+3X^2Y+XY +1. which one is the leading term in this one ?
idk
thanks
This test is gonna be easy
I hate math, but this video is helping, thanks!
my head hurts from all of this
Fr same Ik he is talking abt
thnx
I know I’m 3 years late but what do you do with the negative integer because I always get mixed up
idk
